Specification of Letters Patent. Patented July 2*?, 1915, I original application inea November e, 1905, serial Ne. 285,592.' Divided and this appiieatien iiieapraiiuary' 5,191.4.. seriaiive.810,387'.` J

'by a pitman extending transversely across the front of the machine and operated by a crank-shaft zwhich extends longitudinally of the inachine,-that is to say, fore and aft.

A mower of .this type is shown and described in my pending application, Serial No. 285,592, filed November 2, 1905, of which this application `is a division.

The object of my present invention is to provide improved mechanism for supporting the crank-shaft and for driving the same from the main axle. I accomplish this object as illustrated in the accompanying drawings and as hereinafter described.

l/Vhat I regard as new is set forth in the Claims.

In 'the accompanying drawings, Figure 1 is a plan view, partly broken away, showing thel principal parts of ay mower equipped with my improvements; and Fig. 2 is a sectional view showing the crank-shaft and driving mechanism more in detail.

Referring to the drawings, 3 indicates the main frame of themower which is provided at the rear with a transversely-disposed sleeve 1, through whichr passes the main axle 5. l

l 6 7 indicate the usual' carrying wheels which are mounted upon the rear axle 5 in the usual way.

8 indicates a sleeve rigid withthe frame 3, which is preferably cast as an integral part of said frame and extends fore and aft adjacent to the wheel 7 said sleeve being connected to the sleeve 4 by a housing 9 cylindrical in form, as best shown in Fig. 2.

10 indicates a boss which is joined to the rear end of the housing 9 and extends back of the sleeve 4, as shown in Fig. 1. The forward end of the sleeve 8 is detachably connected with a casting 11 to which is secured one end of aV drag-bar 12, which extends transversely of the machine, as shown in Fig. l. The opposite end of the drag-bar is fitted inl a bracket 13, which is alsconnected to a diagonalbrace 141, as shown in Fig. l, the opposite end of said bracebeing` connected with the frame 3. i

15 indicates the crank-shaft by which the cutter-bar isy reciprocated. As best shown in Fig. 2, said shaft is mounted in the sleeve 8, its forward end being journaled in a suitable bearing provided in the casting 11, while its rear end is journaled in the boss 10 through which it extends.

16 indicates a lnut, screwed upon'the rear end of the shaft 15 and bearing against the boss 10.

17 :indicates a beveled pinion mounted on the shafty 15 at the opposite side of the boss 10 from the `nut 16, or, in other words, within the housing 9. A portion of the periph- 'i ery of said `pinion is, however, exposed through an open side ofsaid housing, asl i shown in Fig. 2.

18 indicates a disk which is mounted upony the forward end of the shaft 15 adjacent to the front bearing of said shaft and `is pro# videdV with a wrist pin 19 to which is connected a pitman 20, which reciprocates the cutter-bar in the usual way.

21 indicates a beveled gear mounted upon a shaft 22 disposed transverselyof the machine, said shaft being' mounted in a bearing 23. The gear 21 mesheswith the pinion 17 and through said pinion drives the 'shaft 15.

241 indicatesa spur-wheel mounted onthe shaft 22 at the opposite' side of the bearing 23 1 from the gearing 21, said spur-wheel meshing with aninternal gear-25 mounted on a sleeve 26, which is Qin turn` loosely mounted on the axle 5. one member' of a clutch, of which 27 is the co-acting member, said member 27 being` Thesleeve 25 forms the beveled gear 21, the latter driving the i pinion 17 and the crank-shaft 15, thereby operating the cutter-bar. By mounting the crank-shaft l5 in the manner described it is supported at both ends and the driving strain is sustained by it between its ends and practically in line with the axle of the machine, thus providing a very strong and serviceable construction. By mounting the crank-shaft in a sleeve rigid with the main frame, it is held in fixed relation to the tongue, and consequently the crank-shaft is prevented from vibrating or swinging vertically independently of the tongue. Furthermore, by arranging the shaft 22 and its gears in the manner described the inward thrust upon the pinion 24 neutralizes the outward thrust on the gear 2l, thus practically balancing said shaft and relieving it of undue strain. The clutch member 27 may be moved out of engagement with the clutch' member 2G by any suitable mechanism, operated either manually or automatically, as described in my said application.

`What l claim as my invention, and desire to secure by Letters Patent, is,-

l. ln a mower, the combination of a frame, comprising a forwardly-extending sleeve rigid therewith, a shaft mounted in said sleeve, front andrear bearings for said shaft, a pinion mounted on said shaft between said bearings, gearing for driving said shaft, and a pitlnan actuated by said shaft. y

9,. ln a mower, the combination of an axle, a housing for said axle, a sleeve rigidly connected with said housing and extending forward from the axle, a shaft mounted in said sleeve, a rear bearing for said shaft adjacent to the axle, a front bearing for said shaft, a pinion mounted on said shaft between said bearings, and gearing adapted to be driven from said axle and meshing with said pinion for driving said shaft.

3. In a mower, the combination of an axle, a main frame supported on said axle, a forwardly-extending sleeve forming a part vof said main frame and rigid therewith, a shaft mounted in said sleeve, front and rear bearings for said shaft, a pinion mounted on said shaft between said bearings, and gearing adapted to be connected with the axle for driving said pinion.

4. In a mower, the combination of an axle, a main frame supported on said axle,

a forwardly-extending sleeve forming a part of said main frame and rigid therewith, a shaft mounted in said sleeve, front and rear bearings for said shaft, a pinion mounted on said shaft between said bearings, and gearing adapted to be connected with the axle for driving said pinion, said gearing comprising a gear meshing with said pinion, a shaft on which said gear is mounted, a spur pinion mounted on the latter shaft, and an internal gear meshing with said spur pinion.

5. ln a mower, the combination of an axle, a housing for said axle, a sleeve rigidly connected with said housing and extending forward therefrom, a boss connected with said housing and extending rearwardly therefrom, a shaft mounted in said sleeve and having a bearing in said boss, a front bearing for said shaft, a pinion mounted on said shaft between its ends, and gearing for driving said shaft from the axle.

6. In a mower, the combination of an axle, a housing for said axle, a sleeve rigidly connected with said housing and extending forward therefrom, a boss connected with said housing and extending rearwardly therefrom, a shaft mounted in said sleeve and having a bearing in said boss, a front bearing for said' shaft, a pinion mounted on said shaft between its ends, gearing for driving said shaft from the axle, and a nut screwed upon the rear end of the shaft and bearing against said boss.

7. In a mower, the combination of a machine frame, a finger-bar, a cutter-bar, a drive-shaft extending longitudinally of the machine, means connected with said driveshaft for reciprocating` said cutter-bar, a beveled pinion mounted on said drive-shaft between the ends thereof, the rear end portion of said drive-shaft being journaled in the machine frame back of said beveled pinion, a front bearing for said drive-shaft, a beveled gear meshing with said pinion, a spur-gear, an internal gear meshing with said spur-gear, and means for driving said internal-gear by the forward motion of the machine.
